Majano-Aiptasia hybrids???

Majano

I agree to the above posts

I was thinking the same thing just hadn't seen any with jagged tentacles and pointed tips, they reminded me of rock flower anemone tentacles. And there's majanos on another rock in the tank that look quite different than these.
Probably lots of variations/colours of Majanos I guess.

There was a post on RC that had the same things just looking for it.

I have a pest destroyer in the mail, trying to figure out what gets blasted first :laser:

Those actually look pretty cool for being a pest lol

Not majano or aiptasia, I forget the name but Ya they're a pest

if you're referring to a laser where did you order from to ensure you actually get it? last time i looked into them it seemed extremely risky and many were being seized at the border.

I'd seen a thread on RC with a photo that looked identical to this but can't seem to find it again. Closest thing I could find is called epicystis sp (rock anemones) They may cease to exist in a few weeks.
And yes I have a " :laser: " on order it's being built right now in Europe and shipped out on Sunday. A little nervous it will arrive but the seller sounds confident so we'll see
